SAFETY INSTRUCTIONS
Driving on Slopes
Driving on slopes is one of the operations
where the risk is greatest that the driver will
lose control or themachine will tip over, which
can result in serious injury or death. All
slopes require extra caution. If you cannot
reverse up a slope or if you feel unsure,
do not mow the slope.
Do as follows
• Remove obstacles such as stones,
tree branches, etc.
• Watch out for and avoid driving over
furrows, holes, and bumps. On uneven
terrain, the machine can tip more easily.
Long grass can hide obstacles.
• Mow up and down, not side-to-side.
• Drive evenly and slowly. Use small
movements of the steering controls.
• Be extra cautious with any additional equipment, which can alter the machine’s stability.
• If the machine stops while going uphill, disengage blades and back down slowly.
Do not
• Do not make sudden changes in speed or direction.
• Do not drive the mower on terrain that slopes more than 10°.
• Do not mow near verges, ditches, or banks. The machine can suddenly spin around if a wheel goes
over the edge of a drop or ditch, or if an edge gives way.
• Do not mow wet grass. It is slippery, and
the tires can lose their grip, so that the
machine slides.
• Do not try to stabilize the machine by
putting a foot on the ground.
• Do not drive near verges or ditches
when cleaning the machine.
• Do not turn on slopes unless necessary,
and then, turn slowly and gradually
downhill, if possible.
• Avoid starting or stopping on a slope. If
the tires begin to slip, shut down the
bladesand drive slowly straightdown the
slope.

CONTROLS
1. Motion Control Levers
The machine’s speed and direction are continuously
variable using the two steering controls. The
steering controls can be moved forward or
backward about a neutral position. Furthermore,
there is a neutral position, which is locked if the
steering controls are moved outward.
When both controls are in the neutral position
(N), the machine stands still.
By moving both controls an equal amount
forward or backward, the machine moves in a
straight line forward or backward respectively.
In order, for example, to turn right while moving
forward, move the right control towards the neutral
position. The rotation of the right wheel is reduced
and the machine turns to the right.
Zero turn can be achieved by moving one control
backward (behind the neutral position) and carefully
moving the other steering control forward from its
neutral position. The rotation direction when zero
turning is determined by which steering control is
moved backward behind the neutral position. If the
left steering control is pulled backward, the machine
turns to the left. Use extra care when using this
manoeuver.
Tracking
If the mower is not tracking straight, check the air
pressure in both rear tires. Recommended air
pressure is 15 psi (1 bar). Tracking must be
checked on a flat and level concrete or blacktop
surface. If unit still does not track straight, contact a
Husqvarna workshop for adjustment.
